However, nonadaptive explanations are also plausible, especially for the positive association observed in industrialized societies. WebSome human characteristics have a narrow norm of reaction, such as blood type. Others have a wide norm of reaction, such as the number of blood cells in humans, which varies depending on factors that include physical fitness, presence or history of infections, and even the altitude at which a person lives. The environment also affects human genes.
